摘要

提出了一种求解三维电磁问题的二阶-四阶空间修正时域有限差分算法。该算法可以使数值相位误差最小化，从而在低分辨率网格下实现高精度。对时谐基本偶极子辐射的长距离传播结果表明，与以往的时域有限差分方法相比，该方法具有低分辨率的优势。

A modified 3D fourth order FDTD algorithm M3d/sub 24/ for improving phase accuracy with low resolution

A second order in time-fourth order in space modified finite difference time domain algorithm for 3D electromagnetic problems is presented. The algorithm enables the numerical phase error to be minimized, so that it leads to high accuracy with low resolution grids. Good results for long distance propagation in the case of radiation from time harmonic elementary dipole show the advantage of this method with low resolution compared to the previous finite difference time domain methods.
